TO ALL WHOM IT MAY CONCERN Be it known that I,`WILLIAM B. RICE, of Utica, in the county of Oneida, and Stateof New York, have invented a new Improvement in Bobbins; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part `of this specification, and represent, in-

Figures 1, 3, and 5, side views of respectively a warp, a filling,`and a twist bobbin.

Figures 2, 4, and 6, respectively, vertical central sections of the same; and in Figures 7, 8, and 9, respectively, lower end Views.' V

lhis invention relates to an improvement in the construction of bobbins, the objectbeing to `overcome the well-knownobjections to the common wood bobbin, andv'to produce a bobbin more durable and free from the aforesaid objections, and consists in forming the spindle from a metallic ltube combined with a hollow metallic base, and also in the peculiar formation of the base of the bohbin whereby the thread upon the start more readily clings to the vhase so that it cannot slip up; and in order to the better understanding of my invention, as well as to enable others to construct the same, I will proceed to a description thereof as illustrated in the accompanying drawings.

The metal which I employ is zinc, and I form the tubes A in like manner as for organ tubes, filling the upper end, B, as seen in figs. 2, 4, and 6, and the upperl end of larger diameter than the base, as in common bobbius, Thebase O isiformed from vthc same metal, only of suicient thickness to afford the necessary strength. The base is former-land secured to the tubes as seen in the several drawings, the tube extending throughand being secured to the bottom plate of the base to form a lower bearing for the spindle. Those of the filling and twist, which, in the ordinary wood bobbins, are provided with a pin, I form with 'a recess or recesses, a, leaving solid parts b for the same object that the pins are set into the wood bobbins, (see'gs. 8 and 9.) The warp-bobbin requiring nothing of this kind, the base is left smooth and apparently solid, as geen in f iig. '7. At the base ot' the warp and filling bobbin I form several shoulders, each shoulder beingthe section of an inverted cone, so that the base of each shoulder is of smaller diameter than at the top. By this arrangement, when the thread is placed at the base and the winding commences, aft-er having p'assed two `or three times around, is prevented by the invertedcone-shaped shoulders from slipping up on the spindle, and no difficulty is experienced at the commencement of the winding as in common wood spindles, neither can the thread, after being wound, slip from. thc bobbin when it is so irmly held at the base, and therefore it is not 4necessary to form the spindle so much larger at the top as. in the common wood bobbin. The shoulders upon the cone5 of the twist-bobbin are formed in like manner, as seen in figs. 5 and 6, and with a like object. Oonstructed in this manner the bobbins are' extremely light, very smooth and durable, do not' absorb the oil, are Very cheap in their construction, cannot be split, a diiiculty so common with a wood bobhin, audwhen, if ever, from accident or otherwise, the spindles may become bruised they are easily repaired to be as goed as new; therefore, costing a trifle more at first, are in the end cheaper by far than the common wood spindles.

Iam aware that metal tubes for bobbins' are not new, and therefore do not broadly claim constructing a bobbin with a metallic tube, but having thus fully described my invention, what I claim as newpand useful, and desire to secure by Letters Patent, is

1. The combination of a hollow metal base, C, with a tubular metal spindle, A, constructed and united substantially as and for the purpose set forth. Y

2. I clainrthe inverted conical shoulders, formed at the base of the hollow spindle, when the said spindle is attached to lthe hollow metallic head, substantially as and for the purpose specilied.'
